(RD. 1, Ridgely, Md. 21660) Filed July 12,1967, Ser. No. 652,939 7 Claims. (Cl. 259-2) ABSTRACT OF THE DISCLOSUREAn apparatus for use in safely mixing poison spray, having a pump forsupplying the mixture from a mixing container to a spray head forspraying field crops and orchards. A blower and filter carries off andcollects spray dust and fumes from the mixing container, during themixing operation, to protect workmen in the vicinity of the apparatus.The pump and blower are connected to the container above the liquidlevel therein during the mixing of the spray. The container is rotatedto locate the pump connection adjacent a bottom part of the containerfor dispensing the spray.

Background of the invention This invention relates to the art of mixingand dispensing poison spray liquids, especially insecticides.

The prior art includes devices which may be utilized for mixing andthereafter dispensing liquid insecticides, but which include no meansfor protecting workmen in the vicinity of the apparatus.

Summary A primary object of the present invention is to provide anapparatus in which poison sprays can be mixed with a maximum safety toworkers in the vicinity of the apparatus.

More particularly, it is an object of the invention to provide means forremoving and collecting poison spray dust and fumes during the mixingoperation.

Another object of the invention is to provide a mixing and dispensingapparatus including a receptacle in which the poison material is mixedwith a liquid, and which includes a pump which is disposed above thelevel of the contents of the container during the mixing operation toprevent clogging of the pump.

Another object of the invention is to provide a mixing container capableof being rotated about its horizontal axis to locate the pump adjacentthe bottom of the container, after the mixing operation has beenaccomplished, and so that the poison spray mixture can be dispensed fromthe container by the pump to a spray head or other discharge outlet.

Various other objects and advantages of the invention will hereinafterbecome more fully apparent from the following description of thedrawings illustrating a presently preferred embodiment thereof, andwherein:

Description of the preferred embodiment Referring more specifically tothe drawings, the mixing and dispensing apparatus in its entirety isdesignated generally 10 and includes an elongated cylindrical container11 which is disposed with its horizontal axis in substantially ahorizontal position and with a portion of its cylindrical side wall 12resting upon a suitable horizontal supporting surface 13. One end wall14 of the container 11 is provided with a segmental shaped opening 15preferably constituting approximately one-fourth of the area of saidwall, as best seen in FIGURE 5.

A rigid angular conduit 16 has one end secured in the side wall 12 andcommunicating with the interior 17 of the container 11. The otherupturned end of the conduit 16 is connected to the inlet 18 of aconventional electric pump 19 which is supported by the conduit 16 atthe side of the container 11. A hose 20 constituting the outlet of thepump 19 leads to any discharge device, not shown, such as a conventionalspray head. A drainage opening 21 is formed in the side wall 12,preferably in the same horizontal plane as the connection of the conduit16 thereto, as best seen in FIGURE 6, and is normally closed by athreaded plug 22.

A rigid angular conduit 23 has one end extending through and secured inthe other end wall 24 of the container 11. The other upturned end of theconduit is connected to the inlet 25 of a centrifugal blower 26 which isI supported by said conduit 23, and which in turn supports an electricmotor 27 of said blower. A hose 28 extends from the outlet 29 of theblower 26 and discharged into one side of a box or receptacle 30 whichhas one or more filter outlets 31 in the opposite side thereof, as seenin FIGURE 7.

The pump 19 may be connected by wiring 32 to any suitable source ofelectric current, such as a storage battery 33, and the motor 37 may beconnected to the same current source 33 by wiring 34. A switch 35 isinterposed in the wiring 32 and a switch 36 is interposed in the wiring34.

With the apparatus in the position as illustrated in FIGURES 1 and 2,the container 11 is filled with a liquid, usually water, up to the levelas indicated by the broken line 37 in FIGURE 5, through the opening 15,which is disposed above said liquid level line. The switch 36 is thenclosed for energizing the motor 27 to operate the blower 26. The poisonspray material, usually in powdered form is then introduced into thechamber 17 through the opening 15 to be mixed with the liquid. Duringthe mixing operation dust and fumes from the spray material will beextracted from the chamber 17 through the conduit 23 by the blower 26and discharged through the hose 28 into the box 30 where said dust andfumes will be collected. The purified air will be separated from thedust and fumes and will escape from the box 30 through the filters 31.As seen in FIGURE 6, the conduit 23 is located above the liquid level 37in the mixing position of the container 11, as seen in FIGURES 2 and 6,and is also located above the liquid level in the dispensing position ofthe container 11, as seen in FIGURE 3. Likewise, as seen in FIGURE 6,the connection of the conduit 16 to the container 11 and the drainopening 21 are disposed above the liquid level 37 in the mixing positionof the container, so that the conduits 16 and 23, the pump 19 and blower26, and the drainage opening 21 will not be clogged by the spraymaterial during the mixing operation.

Aft-er the mixing operation has been completed, the switch 36 isreturned to an opened position to de-energize the motor 27 and thecontainer 11 is rotated counterclockwise about its horizontal axis fromits position of FIGURE 2 to its dispensing position of FIGURE 3 in whichthe conduit 16 and pump 19 are located near the bottom of the container11. The switch 35 is then closed for completing the electric circuit tothe pump 19 so that the mixture can be dispensed by said pump from thechamber 17 through the conduit 16 and hose 20 to a spray head or otherdischarge device, not shown.

Various modifications and changes are contemplated and may be resortedto, without departing from the function or scope of the invention ashereinafter defined by the appended claims.
